Additional Information

Details

Rheem's Prestige series condensing tankless water heaters efficiently provide continuous hot water with a 0.94 energy factor. Condensing technology uses the exhaust gases to reheat incoming cold water which is why they are the most efficient whole home tankless water heating solution available.

Why keep 40-50 Gallons of water hot when you don't need it? It's expensive to continue to heat and re-heat water when you're not home or not using it. Rheem's Prestige tankless design offers convenience and low cost operation.

A mouse destroyed the heat exchanger in my old tank less water heater, and I needed a new one quickly. This new Rheem model provides more water faster and hotter than the old one, and it was cheaper than the one I bought fifteen years ago. It was easy to install with ordinary tools in about three hours. Half of that was removing the old one.

The product specifications and the product description both say "liquid propane" my question is does this unit actually require "liquid propane" or "vapor Propane"? My supply tank is setup for vapor not liquid so I want to make sure the unit will operate on vapor.

HOW TO OBTAIN WARRANTY CLAIM ASSISTANCE

Any claim for warranty assistance must be made promptly. First, determine if your
water heater is in-warranty (that is, within the Applicable
Warranty Period).You can determine your unit's warranty status by adding
its Applicable Warranty Period to its date of installation. However,
if you do not have documentary proof of your water heater's date of
installation, your unit's warranty status will be based on its date of
manufacture. The first four digits of the unit's serial number represent
the month and year it was manufactured. Add the Applicable Warranty
Period plus ninety (90) days to the date of manufacture to determine
whether the water heater is still covered by this Limited Warranty.You
may also determine your unit's warranty status by obtaining the complete
model number, complete serial number, and date of installation of your
water heater and then accessing the Warranty Verification
information on Rheem Water Heaters' internet website (www.rheem.com)
or contacting Rheem Water Heaters' Claims Department (telephone (800)
621-5622) during normal business hours (in the Central Time Zone) to
determine if the Applicable Warranty Period has expired. If your water
heater is in-warranty, contact the plumber, or mechanical
contractor, that installed it for assistance with the warranty repairs,
or replacement, required.You may also select a plumber, or mechanical
contractor, from your local Yellow Pages to assist you. Rheem Water
Heaters' Technical Service personnel are available to assist you (by
telephone at (800) 432-8373 or via e-mail at techserv@rheem.com) in
obtaining in-warranty service or to answer your questions
about the operation or repair of your water heater during normal business
hours (in the Central Time Zone). Be prepared to provide the plumber,
mechanical contractor, or Rheem Technical Service person you call with
the complete model number, the complete serial number, and the date
of installation of your water heater in addition to an explanation of
your water heater problem. If an exact replacement is not available,
Rheem will provide you with the current model of your water heater,
or component part(s), or a replacement unit with comparable operating
features. If government regulations or industry certification or similar
standards require the replacement water heater, or replacement component
part(s), to have features not found in the defective water heater, or
the defective component part(s), you will be charged for the difference
in price represented by those required features. If you pay the price
difference for those required features and/or to upgrade the size and/or
other features available on a replacement new water heater, you will also
receive a complete new Limited Warranty (with the full Applicable Warranty
Periods) for the replacement new water heater. Rheem reserves the right
to inspect, or require the return of, the failed water heater or the
defective component part(s). Each in-warranty failure water
heater must be made available to Rheem (with the rating label and all the
component parts intact) in exchange for the replacement water heater.
Each defective in-warranty component part to be replaced
must be returned to Rheem in exchange for the replacement component part.
Warranty compensation is subject to validation of in-warranty
coverage by Rheem Claims Department personnel.

To obtain warranty compensation for an in-warranty water
heater failure, you must provide Rheem with: (at Rheem's option) either
the failed water heater (with the rating label and all the component
parts intact) or the complete original rating label (photocopies are
not acceptable) removed from the failed water heater; the complete
model number and the complete serial number of the Rheem or Ruud water
heater that replaced the failed unit; and the date the original water
heater failed.You may also be required to provide documentary proof
of the failed water heater's date of installation to establish its
in-warranty status.

To receive warranty compensation for an in-warranty
defective component part, you must provide Rheem with: the defective
component part; the complete model number and the complete serial number
of the Rheem or Ruud water heater from which the defective component part
was removed; and the date the defective component part failed.You may
also be required to provide documentary proof of the date of installation
of the Rheem or Ruud water heater from which the defective part was
removed  or the date of purchase of the part (if it was purchased
